Enzyme induction is the increase of the amount of enzyme due to the effect of a particular stimulus such as a drug. It is in contrast with enzyme inhibition which refers to the restriction of expression of a certain enzyme. Enzyme induction is often associated with pharmacology and molecular biology. For instance, Rifampicin is an antibiotic which stimulates liver enzymes’ production. This drug is prescribed to treat tuberculosis, leprosy, and other bacterial infections.
